What Is 201 Annealed Stainless Steel Plate?

What Is 201 Annealed Stainless Steel Plate?

AISI 201 stainless steel is an austenitic Cr–Mn–Ni alloy, designed as a low-nickel alternative to 304 stainless steel. The annealed condition (soft state) improves its ductility and workability, making it ideal for bending, stamping, and welding applications.

This grade offers good corrosion resistance in mild environments and excellent mechanical strength, making it a popular choice in the automotive, construction, kitchenware, and appliance industries.

 

What does "annealed" mean for stainless steel plates?
Annealing is a heat treatment process that softens the steel, relieves internal stress, and enhances ductility - perfect for fabrication and forming.

Can 201 replace 304 stainless steel?
For dry indoor or non-marine environments, yes. However, 304 or 316 grades are preferred for applications involving moisture, salt, or acids.

 

Does 201 stainless steel rust?
It offers moderate corrosion resistance but may oxidize faster than 304 in aggressive environments. Regular cleaning and passivation help extend its life.

 

Price of 201 Annealed Stainless Steel Sheet (per kilogram)

The price of 201 annealed stainless steel sheet typically ranges from $1.60 to $2.40 per kilogram, depending on factors such as thickness, surface treatment, quantity, and market demand. For example, 201 stainless steel sheet with a 2B surface treatment and a thickness of 1.5 mm to 6 mm typically costs approximately $1,800 to $2,200 per ton on the international market. Prices tend to fluctuate with changes in the cost of nickel and chromium.
